a methodology is presented for the stochastic generation of daily rainfall which accounts for changes to the climatic inputs. the focus of the study is an example catchment in iran. the methodology addresses the inability of gcms to provide suitable future scenarios for the time and space scales required for a water resource impact assessment for a small catchment. one stochastic model for rain...

compost is one of the strategies of house hold solid wastes management that is used to decrease the volume and weight of wastes, odor and leach ate dispersion, resource recycles and decreasing disposal expenses. in order to observe environmental regulations in the frame of adaptation development projects with environmental concerns, assessment of environmental impact of composting plants has be...

This study investigates whether the environmental Kuznets curve (EKC) relationship is supported for a measure of biodiversity risk and economic development across the United States (US). Using state-level data for all 48 contiguous states, biodiversity risk is measured using a Modified Index (MODEX). This index is an adaptation of a comprehensive National Biodiversity Risk Assessment Index. The...

FOREWORD The impact of environmental weeds on the natural environment is an area that has been little studied in Australia. More often than not, impact is assumed rather than quantified. If the impact of environmental weeds on nature conservation values is not quantitatively assessed before a control program is begun, valuable resources can be wasted. For instance, how would it be possible to d...

urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their environmental impact. in a life cycleassessment (lca) the conventional production was used as a yardstick against which tomeasure the performanceof two recycling options: spreading of sewage sludge and phosphorus recovery from municipal ...

the influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. the incorporation of nanoclay into epoxy enhances the impact resistance of the composites. the impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

introduction: air pollution due to particulate matter is a major environmental and health issue in all regions of the world. the aim of this study was to investigate the health impacts of pm10 (particulate matter with an aerodynamic diameter ≤10μm) in khorramabad city, iran in 2014. materials and methods: in this study, pm10 sampling was conducted by a high-volume sampler at flow rate of 1.1-1....
